Metals readily lose and gain electrons, so they rule the list of conductors. Organic molecules are mostly insulators, in part because they are held together by covalent (shared electron) bonds and also because hydrogen bonding helps stabilize many molecules. Most materials are neither good conductors, nor good insulators.
List of Conductors and Insulators A conductor is a substance in which electrons can move freely from one atom to another. An insulator is a substance in which electrons cannot move from one atom to another.
A conductor refers to a material that contains electrical charges on its surface, allowing electricity to flow through it. Most often, these electrical charges are due to the presence of electrons.
In general, metals like copper and aluminum are the best conductors of electricity. Good conductors are able to allow electrons to easily flow through. Metals are typically good conductors because of their ability to donate electrons.
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.
Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
The best conductor of electricity is silver followed by copper and gold due to its crystal structure and bonds. There is a lack of covalent character. It has lattice structure, which allow easier flow of electrons through it.
Most metals conduct electricity. Other elements with high electrical conductivity, are aluminum, zinc, nickel, iron, and platinum. ... For example, sterling silver is not as good of a conductor as pure silver. Oxidized silver is not as good a conductor as untarnished silver. Impurities hinder electron flow.
So it is with electrical conductors, some being better than others. For instance, silver is the best conductor in the "conductors" list, offering easier passage for electrons than any other material cited. Dirty water and concrete are also listed as conductors, but these materials are substantially less conductive than any metal.
Other materials that are sometimes used as conductors are silver, gold, and aluminum. Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver.
